Private Messaging in popup or widget

Hi guys,

I;ve been trying to get 'Chat' plugin to work for a private chat system but found out I had to install 'Friends' too which I can't use on my site because of the emails and need to add a friend first.

So I thought i'd switch to Private Messaging there anyway to have this all in the Popup plugin or show most of it in a widget?

I'm trying to keep users on the front page of the site (due to the nature of the site this is necessary) but can't find a way to do this as PM seems to require a page for everything to work?

Any ideas how I can achieve this ?

Many thanks,
